    add method at runtime with JCompiler ![CODE]

    What is JCompiler?

    This class considerably helps you to compile at the run time. For using it, you should inherit from the JCompiler class, then use the “addFileToWindowsRuntime”, create a new class. Afterward you can create an object from the created class by using JShooter.

    public class Engine extends Maplet {
    public String name;
    public String body;
    public void learning() {
    try {
    new Memory().addMethod("public String " + name +
    "() throws Exception {" + body + "}");
    out.println("Learned.");
    } catch (Exception e) {
    out.println(e.getMessage());
    }
    }
    public void request() {
    try {
    Application app = new Application();
    app.setObject(new Logic());
    out.println(app.invokeMethod(name));
    } catch (Exception e) {
    out.println(e);
    }
    }
    }

    What is your question or problem?

    As it states at the top of the thread list, this is a forum for Java programming questions and answers. Please try to grasp what that means.

    After looking at the example code, I think his question is: "why did I bother to write a useless example to try and advertise my useless product on a programming help forum." After looking as his other 10 posts where he claims that his product can solve every problem, and now apparently it is GREAT for servlets , it is obvious that we all should bow down and add this product to all of our production code. I for one submit to the awesome power of the Jcompiler.

    Re: add method at runtime with JCompiler ![CODE]

    why did I bother to write a useless example to try and advertise my useless product on a programming help forum.
    Given that most of people who frequent sites like this don't have a strong enough understanding of Java to be able to use such a product it can only be to alienate the few of us who might actually have been interested.

    As I said to the OP the other day, the thing to do is to write an article. That way at least the audience are interested in what you have to say.

    What is your question or problem?
    I'd like to know how many times we have to report someone before something is done about it?

    Yes, I'm all in favour of enthusiasts sharing their enthusiasms, but there is a time and place for everything. Pasting a generic "Use this toolkit, it's great!" response to every remotely related question topic is not the way to go.

    As Keang says, writing an article is the way to do it, and will hopefully keep him busy for a while...

    That language is an instrument of human reason, and not merely a medium for the expression of thought, is a truth generally admitted...

    Have some data to back up your claim?

    You don't know what questions I have. Your trivial little example answers what question that "all developers" have?

    Was the question: "man, if there were just some crazy framework that would allow me to write on-the-fly methods in my servlets because I have SOOO many people visiting my website that might want to run their own code on my sever..."

    Was it: "you know, with Spring MVC, Struts 2, JSF and Groovy there just aren't enough frameworks for servlets. does anybody know of one 'has it all' solution?"

    No. Your current approach will only get you onto a bunch of ignore lists or a ban.

    On this forum please restrict yourself to answering explicit Java questions or asking Java questions for which you need an answer. I'm sure there are other forums that are happy to accept unsolicited software recommendations.

    You really don't want to get yourself a bad reputation or a ban on the Java forums - it's a small world.
